PORTSMOUTH — Police arrested a man they claim was responsible for two burglaries at a Port City jewelry store in February.

Authorities arrested James J. Radler, 51, in a hotel in Danvers, Mass., on June 8. Radler was arrested on warrants for jewelry store burglaries that occurred in Beverly, Mass., on Dec. 23 last year and New Year's Day. Radler was arraigned in the Salem Massachusetts District Court and is being held on $750,000 cash bail.

Based on evidence and information received subsequent to Radler's arrest, the Portsmouth Police Department will be filing an arrest warrant for two burglaries that occurred in Portsmouth on Feb. 7 and Feb. 22 at Chrisrial and Company Fine Jewelry at 28 Deer St. in Portsmouth. The suspect in the Portsmouth burglary used a dumbbell to smash a glass doors at the store. A 30-pound dumbbell was used to break both glass doors in the building and was left at the scene.

After breaking both glass doors the suspect gained entry and smashed several glass cases and stole an undisclosed amount of jewelry. The suspect then fled the scene on foot. Portsmouth officers along with a State Police K-9 unit conducted a search of the area, but the suspect was not located.

Video surveillance of the suspect entering the business was obtained. Police also photographed the dumbbell used in the burglary.

Back in February, a New Hampshire state police investigator in the Portsmouth cases said the two Chrisrial smash-and-grab burglaries appeared to be related to eight similar crimes committed in Massachusetts. Lt. Mike Maloney said in both cases a glass door and window were smashed. He says similar burglaries have been reported in the Massachusetts communities of Peabody, Andover and Swampscott.
